Abstract

Objective: Mitral valve surgery can be performed through the trans-atrial or the trans-septal approach. Although the trans-atrial is the preferred method, the trans-septal approach has also been used recently and has a particular value in beating-heart mitral valve surgery. Herein we report our experience with beating-heart mitral valve surgery via trans-septal approach, and discuss its advantages and pitfalls. Methods: Between 2000 and 2007, 214 consecutive patients were operated upon utilizing beating heart technique for mitral valve surgery. The operation was performed via transseptal approach with the aorta unclamped, the heart beating, with normal electrocardiogram and in sinus rhythm. Results: Mean age was 56.03 ± 13.93 years (range: 19-86 years; median: 56 years). There were 131 (61.2%) malesand 83 (38.8%) females. Of the prostheses used, 108 (50.5%) were biological, and 39 (18.2%) were mechanical. Mitral repairs were performed in 67 (31.3%) patients. Mean hospital stay was 17.4 ± 20.0 days (range: 3-135 days; median: 11 days). Intra-aortic balloon pump (IABP) utilization was required in 12 (5.6%) of 214 patients. One-month mortality was 7.4%, and re-operation for bleeding was needed in 15 (7%) patients. Conclusions: Beating-heart mitral valve surgery is an option for myocardial protection in patients undergoing mitral valve surgery. This technique is facilitated by the trans-septal approach due to reduced aortic insufficiency and improved visualization of the mitral apparatus.
